Also, all of the photos from the missions show characteristics of studio lighting. When viewed from a 90 degree angle, shadows from the sun are ALWAYS parallel due to the suns light being millions of miles away. See in this photo that when viewed from the side these shadows diverge at different angles, this is because the large studio light was just out of frame to the left (you can triangulate it’s location)
